Prevalence of acute intestinal infections motivated this research. Cases of intestinal infection at a stationary stage of treatment were analysed in unit of intestinal infection in Infectious Clinical Hospital No. 1 n.a. D.M. Dalmatov in Omsk during the period from 2013 to 2015. Clinical implications of gastroenterocolitis were registered at every second patient with acute intestinal infection, some patients asked for a medical care in late terms. 10.6% of patients have had the virus etiology of gastroenterocolitis, bacteriological etiology was revealed in 2.6% of patients ( Klebsiella pneumoniae, Pseudomonas aeruginosa, Proteus ). The rotavirus infection was more often registered in young people (35.4 ± 8.7 years) with implications of gastroenteritis (37.3%), mainly of moderate severity (82.6%). Salmonellosis appeared in 9.1% of cases with bacteriological verification of Salmonella enteritidis in 86.7% of patients, Salmonella typhimurium - in 8.3%, Salmonella infantis - in 0.8%. More often implications of salmonellosis were registered among the men with a syndrome of gastroenterocolitis of moderate severity who got sick after the use of crude eggs. Acute dysentery and alimentary toxic infection was registered seldom. Every second patient left inpatient department willfully upon application. Thus, the intense situation on a disease of salmonellosis and rotavirus infection remained unchanged in the Omsk region in 2013-2015, however diagnostics of acute intestinal infections was complicated seeing acute inpatient stay in unit that did not allow conducting full examination.
